Power Specifications for the Cisco Nexus 7000 Series Devices

The number of power supplies that a Cisco Nexus 7000 Series switch requires depends on the quantities
and types of modules that you include in the switch chassis. the type of power supply unit that you are
using, and the power redundancy mode that you are using.
The following topics explain how to calculate the device power requirements and the amount of power
available for each type of power supply configuration mode:

Power Requirements for Device Components

To determine the power requirements of the Cisco Nexus 7000 Series switches, add the power
requirements of each of its components. For each component, multiply the number of its modules by its
maximum or typical power requirement. To find the quantities and power requirements for each Cisco
Nexus 7010 switch, see
7018 switch, see
